What is a bootable USB drive?

To some extent, a bootable USB drive is like an installation disc, which contains all the necessary boot files and can be used to boot your computer and troubleshoot in the event of a disaster. You just need to enter BIOS and change boot priority for it. 

Today, on many computers, only the USB interface is reserved, not the optical drive. Thus, bootable device, such as, USB bootable drive, becomes more and more popular. In addition, many users still use it to store files due to its small size and low price.

USB drives mostly are used to store and transfer personal data in old days, thus many users still use the previous way, that is, Copy and Paste, to transfer files from one USB drive to another.

It’s useful if you just want to copy personal files and folders to another USB drive. Assuming that the USB drive contains bootable partition, including its master boot record (MBR), slack space, and any unused space, simply dragging and dropping files to a new flash drive cannot work.

In a word, you can’t just copy and paste files if the USB is a bootable drive. You need to clone bootable USB in Windows 11/10/8/7.
